If `tan^3A+tan^3B+tan^3C=3tanA* tanB*tanC ,` then prove that triangle ABC is an equilateral triangle.

If tan^(3)A+tan^(3)B+tan^(3)C=3tan A*tan B*tan C then prove that triangle ABC is an equilateral triangle.

If, in Delta ABC, tan A + tan B + tan C gt 0 , then the triangle is

in triangle ABC,tan A+tan B+tan C=

In Delta ABC,if tan A+ tan B + tan C= 3sqrt3 , then the triangle is

In a triangle ABC tanA+tanB+tanC>=P then P=

If a tan A + b tanB = (a+b) tan ((A+B)/2) prove that the triangle is isosceles.

If Delta ABC , if tan A + tan B + tan C = 3sqrt(3) , then the triangle is :

If Delta ABC , if tan A + tan B + tan C = 3sqrt(3) , then the triangle is :

In Delta ABC , if tan A + tan B + tan C =3 sqrt3 then the triangle is

Prove that a triangle ABC is equilateral if and only if tanA+tanB+tanC=3sqrt(3).
